Abstract

In this work, the traditional S2 method is applied to measure the differential mode group delay (DMGD) of the polarization-maintaining few-mode fiber (PM-FMF) in two polarization directions, respectively, at the first stage. Then the S2 system is improved to realize a simultaneous DMGD measurement of all LP modes. Results show good consistency when different measurement schemes have been applied. The modified scheme can greatly improve the measurement efficiency by adding only one polarizer. The improvement of the characterization approach for fiber parameters will contribute to the design and the optimization of the PM-FMF.
